    Dear Dr Seow,

    May I know if the attached photo is Eurema andersonii andersonii? Saw it at USR.

    Yes. It is Eurema andersonii.

    Two similar species in which the FW have a single cellspot & the HW spot 7 with a long tail.

    Eurema lacteola lacteola.
    This was first discovered in Singapore, ie Singapore is the type location.
    This seem to have gone extinct in Singapore.
    The FW black border is more deeply excavted in lower space 2 than in space 3.(Similar to E. hecabe.)
    The male is greenish yellow & the female is greenish white.

    Two observations which are possibly Eurema lacteola.

    The inner margin of the FW black border is aligned as in E. lacteola.
    In addition both are strongly greenish & taken in the Central Water Catchment Area.

    Hi Dr Seow,

    I checked through my Singapore Eurema shots and so far nothing suspicious, but I shot one in Sabah (Mahua Waterfall) that seems to fit the description for Eurema lacteola. Lighting wasn't the greatest but does seem to have the slight greenish tinge to it, not as deep yellow as E.andersonii would have. Kept the colours as close to the original shot as possible, would like to hear your thoughts on it. Thank you!

    Post 5.

    Yes. This would also be Eurema lacteola
    The difference between the two are very constant.
    You can also check this out in C&P4. Plate 10, 6, E.lacteola, 7, E. andersonii.

    I am quite confident the two observations from Singapore mentioned, are also E. lacteola.


    TL Seow: Cheers.
